WINDOW.

SPECIFICATION forming part of Letters Patent No. 549,483, dated November12, 1895.

Application filed June 27, 1895.

To all whom, it may concern.-

Be it known that'I, FRANK O. ARMBRUSTER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWVisconsin, have invented new and useful Improvements in Windows, ofwhich the following is a specification.

My invention relates to the construction of windows, and pertainsespecially to certain novel and useful improvements in that form ofconstruction described in the specification forming part of LettersPatent of the United States No. 503,189, issued to me on the 15th day ofAugust, 1893.

The object of my present invention is, first, to provide a more adequatemeans for controlling the movement of the sliding strips and for lockingthem to and releasing them from the sash; second, to provide a moresimple, neat, and durable construction than that heretofore used.

Inthe following description reference is had to the accompanyingdrawings, in which- Figure 1 is an elevation showing my window as viewedfrom the interior of the build ing. Fig. 2 is a similar view with theupper sash removed, and showing the lower sash as it is when swung uponits hinges for the purpose of washing the window. Fig. 3 is a lefthandsection View drawn on the line w m of Fig. 2. Fig. 4 is a section viewdrawn on the line y y of Fig. 1. Fig. 5 is an enlarged detail sectionview drawn on the line 2 e of Fig. 3, and showing the stop for holdingthe left-hand strip in position when the window is swung upon itshinges. Fig. 6 is a detail view showing the knot-engaging bulb of theweight-cords. Fig. 7 is an enlarged view of the section shown in Fig. 3with the center broken away. Fig. 8 is a side view of the right-handedge of the window-sash and strip slightly separated with a portion ofthe side of the strip broken away to disclose the hammer-shaped catch.Fig. 9 is an edge view of the right-hand side of the strip, showing theprojecting lug of the hammer-shaped catch.

Like parts are identified by the same reference-letters throughout theseveral views.

A is the window-casing.

B and B are the lower and upper sash, respectively, each hinged tovertically-sliding strips 0 and O, the latter being arranged to SerialNo. 554,195. (No model.)

move in guideways in the window casing similar 'to those ordinarily usedfor the retention of the sash.

D and D are similarly-disposed strips on the righthand side detachablyconnected with the sash, as hereinafter explained.

The balance-weights are connected to the strips and the sash supportedthereby, as described in my former patent; but my present inventiondiffers from that described in my former patent in the followingparticulars: Referring to the lower sash on the righthand side, the edgeof the sash B is provided with the tongue E,extending from the bottom towithin a short distance from the top of the sash, and the strip D isprovided with a corresponding channel or groove F, into which the tongueE is adapted to fit, as best shown in Fig. 8. Near the top of the sashthis matching is reversed, the strip D being provided with the tongue Eand the sash having the corresponding groove F. Vith this'arrange mentit is obvious that when the sash is raised the strip is necessarilyraised also, moving in the guideway of the window-casing as if formedintegrally with-the sash; but when the sash is lowered it tends to leavethe strip in its raised position,thus freeing the former and permittingit to be swung upon its hinges; but as it is desirable to always holdthe sash and strip together, except when the window is to be swung openor removed, I have pro- Vided the strip D with a two way catch G,somewhat hammer-shaped when viewed from the side, as best shown in Fig.8. This catch is located in a recess R in one side of the strip D andpivotally supported at g, the weight of the catch tending to cause it tohang normally with the claw or hook S projecting in the path of the edgeof the sash. The recess R is covered by a plate T, provided with a slotT, through which the lug U projects from the tip of the claw S, thusproviding means for disengaging the catch from the window-sash.

It will be observed that when the sash and strip are brought togetheralong their entire length the recess H in the sash is opposite the clawor hook S, and the weight of the catch G causes the claw S toautomatically engage in the recess H, thus preventing the sash and stripfrom separating when the former is drawn downward; but it will beobserved that when raised to the position of the strip, as shown in Fig.2, the claw S may be withdrawn from the recess H by pushing on the lugU, thus causing the stop V to engage in the recess I in thewindow-casing. The strip is thereby held securely in its raisedposition, and the sash D can be drawn downwardly until the tongue E iswithdrawn from the channel F, thus permitting the sash to be swung uponits hinges. When the sash is again closed, it is raised alongside thestrip until the tongue E of the sash engages under the tongue E of thestrip,lifting the latter slightly and permitting the catch G to swingforward automatically to release the stop V from the recess I and engagethe claw S in the recess H. The sash and strip can then be movedtogether into place and remain together at all times,except whendisengaged by pressure on the lug U when the sash is in its raisedposition.

J is a button attached to the left-hand side of the casing in the pathof the strip 0, and K is an L-shaped flange attached to the side of thestrip near its top and adapted to engage with the stop M of similarshape attached to the window-casing and adapted to prevent the stripfrom falling outwardly when the lower end of the strip rests upon thebutton, as shown in Fig. 3. The object of this construction is toprevent the win dowsash from falling out when disengaged from the stripD on the right-hand side. The hinged strip being held at the top by theflange K and supported at the bottom by the button J, it is obvious thatthe window may be swung open without falling out, while at the same timeit is supported on the bottom free from contact with the window-sill;but when itis desired to close the window the button is turned to avertical position and is then adapted to fit into the channel N andpermit the strip to be lowered into contact with the sill.

It is obvious that as the sash is lowered past the button the flange Kis released from the stop G, and the sash and strip C can then bereadily removed from the casing, if it is desired to remove the window.

The connecting weight-cord P is inserted through the knot-retainin gbulb Q, the latter being shaped like an inverted cup and adapted to fitinto a recess in the edge of the strip, thus inclosing the knot andpreventing the frayed end of the rope from getting caught between thestrip and the guideway of the casing.

The upper and lower sash being both constructed in the manner hereindescribed, it is obvious that both can be swung into the building andwashed or removed from the casing when it is desired to make repairs.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination with the casing and sash of a window, of thevertically sliding hinged strip located on one side of the window sash,and the detachable sliding strip located on the other side of the sashand provided with the tongue E, and groove F, the edge of the sash beingprovided with the counter-groove F and tongue E, together with a locking device for temporarily holding the strip in engagement with the sash,during the downward movement of the latter, substantially as described.

2. The combination with the casin g and the sash of the window, of thesliding hinged strip located on one side of the window easing and thedetachable sliding strip located on the other side of said casing, theflanges K and M attached to the hinged strip and the window casingrespectively, and adapted to engage with each other when the sash isnear the lower sill, together with the button or stop adapted to holdthe window with said flanges in engagement, when the former is swungupon its hinges, said button or stop being adapted, when turnedvertically, to fit into a channel or recess in the rear of the strip,substantially as described.

In testimony whereof I aflix my signature in the presence of twowitnesses.

FRANK C. ARMBRIRTER.
